VEHICLE-TIRE.

Specification of Letters Patent.

Patented Feb. 17, 1920.

To (all whom if may concern x Be known that l', Josnrn linniro, acitizen of the United States, residing at f wie, in the county oi Erieand State or" i set'ul 'rol'ouing is z.. i his raie more partici aVehicle tire and "ion or resilient Mobiles, trucks ire adapte., i nidthe lili-e.

'"ne ot the objects my inrention this character which or core cresilient material, to take th i the customary iniiated air tube nonconirnonly used i. hin the tire-shoe.

:nother object or' this invention i. to produce a tire which willwithstand the load placed upon it an t the saine time hare `thenecessary res qualities t'or absorbing and neutraliaing shocl-:s due iouneven road surfaces.

Further objects are to reduc a resilient affording tire oi thischaracter which, w p

the advantage of r. iliency, is not affected i aries common to new inuse.

by nunc-Lures or other in) a: Lwic ir ^s anu Which per- Ys circule.LA nor vthe air in the tire 'to lp the same cool and prolong its lire.

ss section on line Fig. 1. cross section on line 3-3, Fig. 1.

Similar characters oic reference indicate corresponding' parts in the`el vier-fs.

i() indicrtes the shoe or ci r casing ot' the tir which may beconstructed of rubber and Ytabric, as usual, and as shown is prei'-erably of the clencher type, although it may vJe air-.f other Well knownconstruction. rlie casing is retained on the rim 11 or' 'the Wheel 12means oit the customary cleneher rino' 13.

The inner structure or core comprising the cushioning or resilient meansarranged within the casing 10 of the tire is prefer- 0 ably constructedas follows:

1st represents a plurality or cushioning blocks or partitions,constructed ot' rubber' or other similar material possessing elastic andresilient qualities. These blocks are shaped, to conform to theconfiguration of the interior of the tire casing so as to lit snuglytherein, as shown in Figs. 2 and 3, and are arranged radially thereotland equally spaced circumferentially of the same, as shown in Fig. 1.The thickness of the cushioning blocks is such that they are capable ofsustaining the tire under given loads, and at the same time alfordingthe necessary resilience to absorb and neutralize the shocks of thevehicle due to road conditions. Fach ot' these blocks is preferablyprovided in its periphery with one or more annular grooves 15 formingspaces between the tire casing and the blocks which permit of thecirculation of air, thereby assisting in keeping the tire cool andretarding the deterioration of the same.

Connecting the seve al cushioning blocks at their outer edges andarranged circumterentially of the tire are spacing Webs 16, preferablyof arcuate or semi-circular form, as shown in Fig. 2, which terminateabout midway of the diameter of the tire casing and conform to theconfiguration of the interior or" the same. These Webs are also proridedin their periphery with one or more groores 17 which are arrangedconcentrically with the blocks and which permit cir` relation of betweenthe tire casing and the Webs and the. spaces between the blocks and alsolighten the same. These Webs are preferably constructed integrally withthe cushioning :blocks 11. A rib 18 n'iay be arranged on the undersideof each of the Webs 1G which connects the adjacent blocks 14 for thepurpose of reinforcing the Webs. The Webs together .,ith thestrengthening ribs 1S prevent displacement of the cushionino" blockscircumerentially of the tire and retain them in a radial position and atright angles to the load and shock imposed upon them.

If desired, the cushioning blocks 14 may be provided with radiallyarranged recesses 19 in their opposite sides, which, as shown in Figs. 1and 2, are deepest at their inner ends and `gradually decrease in depthto- 1iard their outer ends, thereby producing greater resiliencetogether with a lighter construction and less material.

The several elements comprising the core readily applicable to of thecushioning means, namely, the cushioning blocks 14, connecting -Webs 16and ribs Y18, can be molded in one piece, thereby simplifying theconstruction 'of the core cushioning core is accomplished inthe samemanner as the inner tube.

I claim as my invention:

1. A core for cushioned vehicle tires comprising a plurality ofseparatedV resilient blocks and spacing Webs Vconnecting Athe blocks,said blocks being'provided in their convex Y faces with annularventilating grooves.v Y Y Y 2. A core for cushioned vehicle tirescomprising a plurality ofV separated resilient blocks arranged radiallyabout an/aXis, and spacing Webs connecting said blocks, said blocks andWebs being provided in their conveX faces With Ventilating groovesextending transversely of the core.
